Did you know that water is really old?

The water you drink today could be the same water that dinosaur splashed in millions of years ago.

What?

Hello, friends, and welcome back to Sleep Tight Science, a bedtime show that answers your questions about science.

Have you ever wondered what happens to water after it rains?

Or why a puddle disappears on a hot day?

Water is everywhere, in oceans, rivers, lakes, and even in the air we breathe.

It's one of the most important things on earth, because every living thing needs water to survive. But water doesn't just sit still, it's always moving, changing, and traveling through a process called the water cycle.

You'll discover how water disappears into the air, forms clouds, falls back to the earth as

rain or snow, and finds its way back to rivers, lakes, and oceans, only to start the journey
